Grizzly H7868 - Compression Tapping
Includes G74 and G84 tapping cycles, for use with a tension/compression (floating) tap holder. These cycles reverse the spindle at the bottom of the hole, but do not rigidly slave the Z axis feed to the spindle rotation.
You need to have programmable spindle speed control in order to use compression tapping. You do not need a spindle encoder.
You do not need the Compression Tapping cycles in order to tap with a self-reversing tap head (e.g. TapMatic or Procunier). With a self-reversing head you use the G85 boring cycle. G85 is part of the Drilling Cycles option.
